s3, enabling the metal wire to penetrate through the wire guide pipe (6), to bypass the wire inlet roller (19), to penetrate through the wire inlet hole (22) from the lower part of the cutter head (21), to be sequentially attached with the arc pressing block (25), the first wire roller (15) and the second wire roller (17), to penetrate through the wire outlet hole (18), and to penetrate through the second positioning hole (12) and to spot-weld the end of the metal wire on the surface of the metal arc sheet (8) for fixing;
s4, loosening the bolt I (14), adjusting the front and rear positions of the fixing rod (16) to enable the cutter head (21) to enter the inner cavity of the through plastic pipe (13) and be located at the position of the circumference where the second positioning hole (12) is located, and then tightening the bolt I (14);
loosening the bolt II (24), finely adjusting the angle of the line pressing guide block (23) to ensure that the depth of the groove formed on the inner wall of the straight-through plastic pipe fitting (13) by the tool bit (21) is 0.8-1 times of the diameter of the metal wire, the width of the groove is 0.1-0.3 mm smaller than the diameter of the cable, and then screwing the bolt II (24);
step S5, firstly, the rotating motor (10) is started to drive the through plastic pipe fitting (13) to rotate, and the cutter head (21) is attached to the inner cutting groove of the through plastic pipe fitting (13); then, starting the stepping motor (1) to drive the sliding table (4) to move forwards on the track (3); the rotating motor (10) and the stepping motor (1) work synchronously to drive the cutter head (21) to cut a spiral groove on the inner wall of the straight-through plastic pipe fitting (13), and the arc pressing block (25) synchronously presses the metal wire into the spiral groove;
and step S6, after t minutes, when the cutter head (21) reaches the position of the first positioning hole (11), the rotating motor (10) and the stepping motor (1) are closed, the three-jaw chuck (9) is loosened, after the inner wall of the through plastic pipe (13) and the cutter head (21) are separated, the stepping motor (1) is started to rotate reversely, the sliding table (4) drives the cutting device (7) to withdraw from the through plastic pipe (13), and then the metal wire is drawn out of the positioning hole (11) and cut off, so that the winding work of the embedded metal wire is completed.
